cooled roller and the water cooled table, and

the principal objects of the present inven- Y tion are, first, to decrease the supply of water required and increase the heat exchange effected, and second, to apply the water where it will be most effective in carrying away heat to keep the temperatures at different parts of the roller or table sufficiently alike to avoid warping and the consequent defects in the rolled sheets.

The invention will be claimed at the end hereof but will be first described in connection with the embodiments of it chosen for illustration in the accompanying drawings forming part hereof and in which- Figure l, is a transverse sectional view of a water cooled table embodying features of the invention.

Fig. 2, is a longitudinalsectional view of the same.

Fig. 3, is a top or plan view of the table with parts broken away.

Fig. 4, is an end viewof the table with parts broken away.

Fig. 5, is a View, partly in section, of a roller embodying features of the invention.

Figs. 6 and 7, are an end view of a roller with parts removed and a cross section of the same, and

Figs. 8 and 9, are views, with parts broken away, of solid and hollow rods. U

In the drawings the element for rolling glass is shown as a table l, Figs. 141:, and as a roller 2, in Figs. 5-7. In each case the element is provided throughits body with' water channels 3, and there are inlet and Voutlet water connections or headers 4,

Shown as common to allthe channels 3. InV

the channels 3, are loosely arranged rods 5, of less cross-section than the channels and these rods may be solid as shown inFig. 8, or hollow and stopped at the ends as shown in Fig. 9.

In the case of the table and of the roller because the rods, by gravity,

the channels 3, are shown as circular in cross-section and the rods are shown as of similar but smaller cross-section. That is the natural and most easily manufactured form of cross-section but it might in some cases be departed from. The differences in the size of the cross-.section is important because this difference in size provides water spaces 6, and these water Spaces are shown as crescent shaped.

E'ther worln'ng face of the table may be turned uppermost and used to roll glass on, and the respective faces are usually provided with different designs. No matter V which face is turned uppermost the portion of the water space 6, of largest cross-sectional area is adjacentto the top Where it is found to produce the best result with the least water, and this occurs automatically will occupy the lowest position in the channels. In the case of the roller many of the advantages are the same although the rods will constantly shift their position in the channels as the roller revolves. The generally crescent shape in cross-section `of the water passages insures the application of the water in thin streams of large area and soa limited supply of water can be most effectivelyapplied for cool-v ing purposes.

In referring to glass as the substance to be rolled by the described machinery, I desire to include the use of the machinery for other equivalent purposes.

I claim:

1. A table for rolling glass provided through its body with water channels circular in cross-section and having inlet andout- -let water connections, and rods of less circu? lar cross-section than the channels arranged for rolling therein, to provide crescent `shaped water spaces near the top surface of thetable whichever of its working surfaces Vis uppermost.

, 2.`A table for rolling glass provided 'through its body with water channels and ARNO SHUMAN.
